Work Experience

Software Engineer

Paytm

Dec 2024 - Apr 2026

Owned development of RESTful APIs built on Spring Boot microservices for core merchant onboarding workflows handling 400+ TPS, ensuring high-throughput and scalability. Designed a Redis-based distributed queue leveraging Sorted Sets for load-driven agent allocation, integrated third-party APIs (Udyam Aadhaar), and implemented enterprise QC workflow optimizations aligned with SOPs, reducing turnaround time (TAT). Engineered an asynchronous bulk merchant update and job replay pipeline, moving file processing to background workers and enabling non-blocking API responses. Provided on-call production support via Kibana and Grafana for monitoring and root cause analysis, maintaining high availability and SLAs compliance while collaborating with cross-functional teams on incident resolution. Worked across the full SDLC including requirement analysis, solution design, development, code reviews, and integration testing — following Agile/Scrum methodologies while applying Cursor AI for coding, refactoring, and debugging to accelerate delivery.

Architected and maintained Spring Boot microservices and enhanced payment gateway integrations (Stripe and PayPal), reducing refund and dispute cases from 30 to 5 per day. Extended Stripe and PayPal integrations via RabbitMQ to process payments and subscription webhooks, and utilized Redis caching to minimize redundant API calls and reduce response latency. Standardized API contracts and technical design documentation in Confluence for product features, supporting knowledge sharing, troubleshooting, mentoring new team members, and cross-functional collaboration. Developed and delivered RESTful backend services in Golang, Gin Web Framework, and GORM, improving scalability across core services. Shipped 15+ proofs of concept (POCs) and production features, including a short-URL service and device uptime calculation for billing cycles, applying clean architecture and design-pattern best practices. Resolved production issues and enforced SOP-aligned request validation, improving application reliability and increasing unit test coverage to 95%, resulting in a 20% reduction in issue recurrence.
